LOOSE LEAF BINDER.

Specification of Letters Patent.

Application filed November 17, 1916. SeZ'iaI'NO. 131,81

Z?) of? whom. it may concern:

lie it known that l, CLARENCE D. TRUS- ssLL, a citizen of the United States, residing in Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Loose- Leaf Binders, of Which the following is a specification.

invention relates to a loose leaf bind ing mechanism and particularly to that type of device wherein a plurality of prongs or hooks or half rings are mounted on hook plates which are pivotally supported and are spring held in either open or closed position. lily invention has for its object to provide an. improved and simple construction of such liaise leaf binder. A further object of my invention is to improve the means of attaching the bindorto the cover, and likewise to improve the construction of hook.

Desirable forms in which my invention Y may be embodied are illustrated in the acconpanying drawings, wherein,- Figure l is a perspective view en'lbodyi ng my invention Tie. 52 is a sectional detailed view thereof 1 l on the line 2-2 of Fig. 1;

modified form of device; "l' is a sectional view of a further nation; 4 8 is a back view of my device; Fig. 9 and Fig. 10 are perspective views ol' huhs employed to attach the binding nicc ll'llSJIl to the cover-pend 11. is a'face view of the hook plates detned in the modification illustrated in Fi "2. I

.Plecording to my invention means are pro vided for supporting the hook plates and holding them by spring means in open or closed position, which are greatly simplified. or this purpose but two elements are necesthe heel and (2) a support- I ate in which the hook plates are iviountcd. These with the spring are are essenthl for the I." .nical operation ot the device, althktiu hates 'ot lugs C,

111 Fig. 6, and these flanges,

of a binder I also prefer to employ a back plate which is suitably secured to the supporting providenieans for conveniently attaching the device to the cover.

In the embodiment of my invention shown in the accompanying drawings the hook plates A A are pivotally supported at or near their outer ends in a flat supporting plate l3. Such pivotal'support of the hooks in the said plate may be provided by means with which each hook plate is furnished adjacent its outer edge, and each hook plate preferably has a plurality of the said lugs, and these lugs may pass through perforations C in the supporting plate. If desired such pivotalsupporting means may otherwise be furnished as by means of flanges D with which each edge of the supporting plate may he provided as illustrated as they are shown, extend downwardlyand serve to our brace the outer edges of the hook plates.

he spring means for causing the hook plates to pass to either open or closed position and to be held in such position, C0111- prise projections E with which each hook plate is provided adjacent its inner edge. As illustrated, such projections are in the form of lugs bent up from the material of plate. The pro ections E on the respective plates are preferably arranged in groups,

and each group should have projections so arranged that a one plate is located between wo projections on the opposite plate, as is clearly shown in Fig. 3. Any desired number of groups may be employed and any desired number of projections greater than three in each group. The spring means employed by me may be of various terms. As illustrated, such spring means takethe form or a spring rod at least three projection on constructed.

fore been employed for G which is longitudinally disposed between the respective projections at or near the ends thereof, and for this purpose one or more 0 said projections may be provided with notches or anchorages G to hold the said rod in place.

In the forms of my invention illustrated in Figs. 4:, 5 and 6 the supporting plate is on .top and the hook plates are located beneath the supporting plate, and this furnishes a very desirable and convenient arrangement of parts. It is not, however, indispensable to the employment of my invention, as I have shown in Fig. 7 a construction wherein the hook plates are located above the supporting plate, the parts being otherwise similarly In the form of my invention illustrated in Figs. 4:, 5 and 6 the respective movements of the hook plates are limited as follows: The opening movement is limited by the contact of the hook plates with the under side of the supporting plate; the closing movement is limited by contact of a pair of the hooks H which each of the hook plates carries. In the form of my invention illustrated in Fig. 7 wherein the hook plates are disposed above the supporting plate means must be provided to limit the opening movement of the hook plates, and for such purpose the lugs I are well adapted and have heretoa similar purpose. 8% for instance my Patent No. 1,141,157. Each hook plate is provided with one or more of the lugs I, andv these lugs extend down through the opening E in the hook plate and each has its free end located beneath the opposite hook plate so that upon the opening movement such lugs will by contact with the underside of the supporting plate B limit the opening movement of the hook plates.

My invention means for attaching the loose device invented by me to the cover. illustrated the device as being provided contemplates improved I have with a cover J which may be any one of the designs of covers usually employed. For the purpose of enabling the attachment of the parts to be easily made, I have illustrated the employment of a. back plate K which is providcd with longitudinal edge flanges 7.; that are adapted to hold the back plate in position upon the supporting plate B. The said attaclling means comprise metallic hubs L of which any suitable number may be employed. In Fig. 8 I have illustrated the employment of five such hubs. These hubs may well be used in connection with a binding plate' and by means of which the hubs M are firmly clamped to the back of the cover J. Other means might be employed for this purpose, or if desired the hubs M might be directly clamped to thc binding mechanism. but the arrangement which I have illustrated is a desirable one and convenient and economical wherein two sue leaf binding 1 for purposes of manufacture. Each hub L is preferably curved longitudinally for the purpose of conforming to the shape of the binding plate X, the back plate K and the back of the book. Each of the said hubs has a portion M which is located outside of the back of the cover J The hubs have side flanges N which pass through cuts in the cover J, leather being frequently employed for such cover. Upon the said side flanges are lugs O which are bent down on the binding plate X as illustrated in Fig.2 and securely hold the parts together. Any desired number of said lugs 'on the hubs may be em ployed. I prefer to employ a plurality of lugs on each side as illustrated in Fig. 10 shown. The bindiii'g plate X is provided with lugs Y which pass through slots in the back plate and are bent down to secure the binding mechanism to the cover.

I have illustrated in the accompanying drawings the most desirable form of my invention now known to me, but the same may be modified and changes made therein, and equivalent devices substituted for those illustrated, within the limits of the appended claims.
